CVE-2026-53115 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
bus: fsl-mc: use generic driver_override infrastructure
When a driver is probed through __driver_attach(), the bus' match() callback is called without the device lock held, thus accessing the driver_override field without a lock, which can cause a UAF.
Fix this by using the driver-core driver_override infrastructure taking care of proper locking internally.
Note that calling match() from __driver_attach() without the device lock held is intentional. [1]
